Abstract:

The algorithm of one-dimensional address code cross-correlation value was given from the shift of discrepancy of location "1" of arbitrary two codes among code focusing will occur the collision of "1". By using this method, analyze some of the typical one-dimensional code cross-correlation value distribution, and on this basis, verify the front part of text to seek the average cross- correlation value formula by using the probability analysis method, then on the basis of one-dimensional address code analysis, give the algorithm of the symmetric two-dimensional code cross-correlation value distribution.
